This is circle based question from Chapter name- circles
Topic – Angle properties of circles
Chapter number- 15
In this question we have, O is the centre of the circle and SP is a tangent.
∠SRT = 65°, and by using these we have to find the value of x, y and z.
This question has been asked in 2015.
In the second part of the question we have O is the centre of the circle. PS and PT are tangents and ∠SPT = 84°.
Now we have to calculate the sizes of the angles TOS and TQS.
